Public Methods

Method	Description
Matches ( ActualValueDelegate del ) : bool	Converts an ActualValueDelegate to a TestDelegate before calling the primary overload.
Matches ( object actual ) : bool	Executes the code of the delegate and captures any exception. If a non-null base constraint was provided, it applies that constraint to the exception.
ThrowsConstraint ( NUnit.Framework.Constraints.Constraint baseConstraint ) : System	Initializes a new instance of the T:ThrowsConstraint class, using a constraint to be applied to the exception.
ToString ( ) : string	Returns the string representation of this constraint
WriteActualValueTo ( MessageWriter writer ) : void	Write the actual value for a failing constraint test to a MessageWriter. The default implementation simply writes the raw value of actual, leaving it to the writer to perform any formatting.
WriteDescriptionTo ( MessageWriter writer ) : void	Write the constraint description to a MessageWriter

Method Details

Matches() public method

Converts an ActualValueDelegate to a TestDelegate before calling the primary overload.

public Matches ( ActualValueDelegate del ) : bool
del	ActualValueDelegate
return	bool

return	bool

ThrowsConstraint() public method

Initializes a new instance of the T:ThrowsConstraint class, using a constraint to be applied to the exception.

public ThrowsConstraint ( NUnit.Framework.Constraints.Constraint baseConstraint ) : System
baseConstraint	NUnit.Framework.Constraints.Constraint	A constraint to apply to the caught exception.
return	System

ToString() public method

Returns the string representation of this constraint

public ToString ( ) : string
return	string

WriteActualValueTo() public method

Write the actual value for a failing constraint test to a MessageWriter. The default implementation simply writes the raw value of actual, leaving it to the writer to perform any formatting.

public WriteActualValueTo ( MessageWriter writer ) : void
writer	MessageWriter	The writer on which the actual value is displayed
return	void

WriteDescriptionTo() public method

Write the constraint description to a MessageWriter

public WriteDescriptionTo ( MessageWriter writer ) : void
writer	MessageWriter	The writer on which the description is displayed
return	void
